Ukuhlaziywa Kwesakhiwo Nokwakheka Kwamaplanethi Esimisweni Selanga Uhlelo lwelanga luyisimiso esiyinkimbinkimbi samandla adonsela phansi, esihlalwa amaplanethi ayisishiyagalombili, amaplanethi amafushane, ama-asteroid, ama-comet, nezinye izinto ezincane ezahlukahlukene, zonke ezizungeza iLanga. Phakathi kwalezi zinto, amaplanethi abaluleke kakhulu ngoba izakhiwo zawo zangaphakathi ezahlukahlukene kanye nokwakheka kwawo kubonisa ukwakheka kokuqala kwesistimu yelanga. Ukuhlaziywa… Funda kabanzi

Incazelo Ephelele Yemigodi Emnyama: Imigodi emnyama iphakathi kwezinto ezithakazelisayo kakhulu nezidlulele endaweni yonke. Zihlanganisa imfihlakalo, ubuhle befiziksi, kanye nemikhawulo yokuqonda komuntu isikhala nesikhathi. Ngamazwi alula, imbobo emnyama yindawo emkhathini enamandla adonsela phansi kangangokuthi akukho lutho—ngisho nokukhanya—olungaphunyuka. … Funda kabanzi

Indlela Ilanga Elithinta Ngayo Isimo Sezulu Somhlaba Ilanga liwumthombo oyinhloko wamandla oMhlaba. Cishe zonke izinqubo ezibumba isimo sezulu nesimo sezulu—kusukela ekuhwamukeni kolwandle kanye nokwakheka kwamafu kuya ekujikelezeni komoya kanye ne-photosynthesis—ziqala ngokukhanya kwelanga okufinyelela emkhathini nasebusweni beplanethi yethu. Kodwa-ke, ithonya leLanga esimweni sezulu alilula njengoba “lapho kushisa kakhulu.” Kunezindlela eziningi... Funda kabanzi

Amaqiniso Athakazelisayo Ngeplanethi I-Jupiter I-Jupiter iyiplanethi enkulu kunazo zonke ohlelweni lwelanga futhi ingenye yezinto ezihlaba umxhwele kakhulu esibhakabhakeni sasebusuku. Ngobukhulu bayo obukhulu, umoya onesivunguvungu, kanye namasathelayithi amaningi ayizungezayo, i-Jupiter ivame ukubizwa ngokuthi "inkosi yamaplanethi." Kodwa-ke, ngemuva kwedumela layo elihle, i-Jupiter inamaqiniso amaningi athakazelisayo anabososayensi... Funda kabanzi

Umehluko Phakathi Kwezinkanyezi Nezinkanyezi Abantu abaningi basahlanganisa izinkanyezi kanye nezinkanyezi ngoba zombili zibhekana nesibhakabhaka, izinkanyezi, amaplanethi, kanye nezimo ezahlukahlukene zasemkhathini. Kodwa-ke, zinezinhloso, izindlela, kanye nemibono eyisisekelo ehlukene kakhulu. Izinkanyezi ziyigatsha lesayensi elifundwa ngokwesayensi futhi elisekelwe ebufakazini, kuyilapho izinkanyezi ziyisimiso sokukholelwa noma umkhuba wokuhumusha... Funda kabanzi

Indlela Yokubona Izinkanyezi Esibhakabhakeni Sasebusuku Ukubuka isibhakabhaka sasebusuku bekulokhu kunobuhle baso obuhlukile. Ngemuva kokukhanya kwezinkanyezi okubonakala kungahleliwe, empeleni kunezindlela ezithile abantu abaye baziqaphela njengezinkanyezi iminyaka eyizinkulungwane. Izinkanyezi zisiza amatilosi ukuba ahambe, abalimi banqume izinkathi zonyaka, kanye nososayensi bamamephu esibhakabhakeni. Kodwa kwabaqalayo, ukuthola "isithombe" sezinkanyezi phakathi...

I-Big Bang Theory kanye Nomsuka Wendawo Yonke Umbuzo wokuthi indawo yonke yavelaphi udonse isintu izinkulungwane zeminyaka. Kusukela ezinganekwaneni zasendulo kuya ezifundweni zesayensi zanamuhla, ilukuluku mayelana "nesiqalo" alikaze linciphe. Ku-cosmology, incazelo eyamukelwa kabanzi namuhla yi-Big Bang Theory, umqondo wokuthi... Funda kabanzi

Indlela Ama-Telescope Asebenza Ngayo Ku-Astronomy Ama-Telescope angenye yamathuluzi abaluleke kakhulu ku-astronomy. Ngenxa yama-telescope, abantu bangakwazi "ukukhulisa" ikhono leso lokubona izinto zasezulwini ezikude kakhulu nezingabonakali—kusukela eNyangeni, amaplanethi, ama-nebulae, kuya emithaleni eqhele ngezigidigidi zeminyaka yokukhanya. Kodwa-ke, abantu abaningi bacabanga ukuthi ama-telescope asebenza nje njengezibuko ezinkulu zokukhulisa. Eqinisweni, isimiso... Funda kabanzi

Imibono Ngokwakhiwa Kwama-Asteroid Nama-Comet Ama-Asteroids nama-comet ayizinhlobo ezimbili zezidalwa ezincane zasezulwini eziye zadonsa ukunaka kwezazi zezinkanyezi isikhathi eside. Zivame ukubizwa ngokuthi "izinsalela" kusukela ekwakhekeni kweSistimu Yelanga ngoba zakhiwa ezinsukwini zokuqala lapho iLanga namaplanethi kwase kusanda kuqala ukwakheka. Nakuba zombili zincane kakhulu kuneplanethi, ama-asteroid nama-comet anomehluko omkhulu... Funda kabanzi

Indlela I-Astronomy Esetshenziswa Ngayo Emivubukulweni I-Astronomy kanye ne-archaeology kuvame ukubhekwa njengemikhakha emibili ehlukene kakhulu: enye ifunda amazulu, kanti enye ihlola imikhondo yokuphila komuntu kwangaphambilini. Kodwa-ke, empeleni, lokhu kokubili kungaphelelisana. Lapho abavubukuli bethola izakhiwo zasendulo ezibonakala “zikhomba” endaweni ethile emkhathizwe, noma lapho indawo… Funda kabanzi
